Beginning (b)(6) 2012, us and (b)(6) customers were sent an urgent patient safety advisory informing of the need for proper care and preventive maintenance of their zimmer electric dermatome.Customers were informed that improperly maintained instruments may cause donor site injuries or result in damage to the graft.Customers were requested to contact zimmer to schedule maintenance for the device in accordance with the instructions for use.The device was returned to the manufacturer for repair and evaluation.The service record indicates that the device was manufactured on 07/11/1995, and was last repaired on 02/16/2010 for a non-related issue.Evaluation of the device confirmed the device to operate intermittently, as operation ceased after the third power cycle.In addition, the width plate screws were missing and the reciprocating arm and thickness control lever were older style components.Prior to repair, the device was outside calibration specifications only at the zero thickness setting on the left side, and side to side calibration.In post-repair, corrosion of the exterior motor casing was observed.The motor operated within motor voltage specification and the power switch passed a continuity test.Customer did not return a power supply for evaluation.Lack of preventative maintenance most likely allowed the damage to the motor to occur over time and improper handling related to cleaning or sterilization of the unit most likely allowed moisture to enter the handpiece, corroding the motor over time.The device was serviced and returned to the customer.
